PRECAUCIONES DE SEGURIDAD
ADVERTENCIA: Antes de dar servicio a este chasis, lea "PRECAUCIONES RESPECTO A RADIACION POR RAYOS X",
"INSTRUCCIONES DE SEGURIDAD" y "AVISO SOBRE SEGURIDAD DE PRODUCTOS"
INSTRUCCIONES DE SEGURIDAD
1. Cuando el receptor está en operación, se producen voltajes
potencialmente tan altos como 25,000-29,000 voltios. Operar
el receptor fuera de su gabinete o con la tapa trasera
removida puede causar peligro de choque eléctrico.
(1) Nadie debe intentar dar servicio si no está debidamente
familiarizado con las precauciones que son necesarias
cuando se trabaja con un equipo de alto voltaje.
(2) Siempre descargue el ánodo del tubo de la imagen a tierra
para evitar el riesgo de choque eléctrico antes de remover
la tapa del ánodo.
(3) Descargue completamente el alto potencial del tubo de
imagen antes de manipularlo. El tubo de la imagen es de
alto vacío y, si se rompe, los fragmentos de vidrio salen
despedidos violentamente.
2. Si se quemara algún fusible de este receptor de televisión,
reemplácelo con otro especificado en la lista de partes.
3. Cuando reemplace tableros o plaquetas de circuitos,
cuidadosamente enrolle sus alambres alrededor de las
terminales antes de soldar.
4. Cuando reemplace un resistencia de vataje (resistor de
película de óxido metálico) en el Tablero o Plaqueta de
circuitos, mantenga la resistencia a un mínimo de 10mm de
distancia.
5. Mantenga los alambres lejos de componentes de alto voltaje
o de alta temperatura.
6. Este receptor de televisión debe conectarse a una fuente de
100 a 240 V AC.
7. Antes de devolver este aparato al cliente, haga una
verificación de fuga de corriente sobre las partes metálicas
del gabinete expuestas, tales como antenas, terminales,
cabezas de tornillos, tapas de metal, palancas de control etc.,
para estar seguro de que el equipo funciona sin peligro de
choque eléctrico. Enchufe el cordón directamente al
tomacorriente de la línea de AC 100-240V.
No utilice una línea aislada de transformador durante esta
verificación. Use un voltímetro de 1000 Ohmios por voltio
de sensibilidad o más, en la forma que se describe a
continuación.
Cuando la unidad está ya conectada a la AC, pulse el
conmutador primero poniéndolo en "ON" (encendiendo) y
luego en "OFF" (apagando), mida desde un punto de tierra
conocido, tal como una (cañería de metal, una manija
metálica, una tubería etc.) a todas las partes metálicas
expuestas del receptor de televisión (antenas, manijas de
metal, gabinetes de metal, cubiertas de metal, palancas de
control etc.,) especialmente cualquiera de las partes
metálicas expuestas que puedan ofrecer un camino hacia el
chasis. Ninguna medición de corriente eléctrica debe exceder
de 0.5 miliamperios. Repita la prueba cambiando la posición
del enchufe en el tomacorriente. Cualquier medición que no
esté dentro de los límites especificados aquí representan un
riesgo potencial de choque eléctrico que debe ser eliminado
antes de devolver el equipo al cliente.

AVISO SOBRE SEGURIDAD DE PRODUCTOS
Muchas de las partes, electricas y mecánicas en este chasis tienen caracteristicas relacionadas con la seguridad. Estas
caracteristicas frecuentemente pasan desapercibidas en las inspecciones visuales y la proteccion que proporcionan contra la
RADIACION DE RAYOS-X no siempre necesariamente se obtiene al mismo grado cuando se reemplazan piezas o componentes
diseñados para voltajes o vatajes mayores, etc. Las piezas que tienen estas caracteristicas de seguridad se identifican por la
marca
impresa sobre el diagrama esquematico y la marca ★ impresa en la lista de partes. Antes de reemplazar alguno de
esos componente, lea cuidadosamente la lista de este manual. El uso de partes de reemplazo que no tengan las mismas
caracteristicas de seguridad, como se especifica en la lista de partes, puede crear Radiacion de Rayos-X.

4. PCB assembly adjustment method
(Using MSTAR Download program)
1. Application Range
These instructions are applied to all of the LCD TV, LP81A
Chassis.
4.1 S/W program download
2. Notice
2.1 Because this is not a hot chassis, it is not necessary to
use an isolation transformer. However, the use of
isolation transformer will help protect test instrument.
2.2 Adjustment must be done in the correct order.
2.3 The adjustment must be performed in the circumstance of
25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.
2.4 The input voltage of the receiver must keep 100~220V,
50/60Hz.
2.5 Before adjustment, execute Heat-Run for 15 minutes at
RF no signal.
4.1.1 Preliminary steps

- We confirm whether "0xF3 (offset), 0xF4 (gain)" address of
EEPROM "0xBC" is "0xAA" or not.
- If "0xF3", "0xF4" address of EEPROM "0xBC" isn’t "0xAA",
we adjust once more
- We can confirm the ADC values from "0x06~0x0B"
addresses in a page "0xBC"
*Manual ADC process using Service Remocon. After enter
Service Mode by pushing "ADJ" key, execute "Auto-RGB"
by pushing "_" key at "Auto-RGB".
3. Select "Start" Button and press "ok" button
Updating is staring.
4.2.2 Component input ADC

5. Adjusting the White Balance
6. Adjustment of White Balance
5.1 Purpose and Principle for adjustment of the
color temperature
- Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
- Principle : To adjust the white balance without the
saturation,
(Fix the one of R/G/B gain to C0 and decrease the others.)
5.2 Adjustment mode : Two modes of Cool and Warm
(Medium data is automatically calibrated by the
Cool data)
O Required Equipments
- Remote controller for adjustment
- Color Analyzer : CA100+ or CA-210 or same product
LCD TV( ch : 9 ),
- Auto W/B adjustment instrument(only for Auto adjustment)
5.3 Connecting diagram of equipment for
measuring (For Automatic Adjustment)
• Adjustment mode : Two modes (Cool and Warm)
(Medium data is automatically calibrated by the Cool data)
• Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000
(LCD : CH9, PDP : CH10)
• Operate the zero-calibration of the CA100+ or CA-210, then
stick sensor to the module when adjusting.
• For manual adjustment, it is also possible by the following
sequence.
1) Select white pattern of heat-run by pressing "POWER ON"
key on remote control for adjustment then operate heat run
longer than 15 minutes.
(If not executed this step, the condition for W/B may be
different.)
2) Push "Exit" key.
3) Change to the AV mode by remote control.(Push front-AV
or Input key)
4) Input external pattern(85% white pattern)
5) Push the ADJ key two times (entering White Balance
mode)
6) Stick the sensor to the center of the screen and select
each items (Red/Green/Blue Gain and Offset) using /
(CH +/-) key on R/C..
7) Adjust R/ G/ B Gain using / (VOL+/-) key on R/C.
8) Adjust two modes (Cool and Warm)
(Fix the one of R/G/B and change the others)
9) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.
(1) Enter the adjustment mode of DDC
- Set command delay time : 50ms
- Enter the DDC adjustment mode at the same time heat- Maintain the DDC adjustment mode with same condition
of Heat-run
-> Maintain after AC off/on in status of Heat-run pattern
display)
(2) Release the DDC adjustment mode
- Release the adjust mode after AC off/on or std-by off/on
in status of finishing the Hear-run mode
- Release the Adjust mode when receiving the aging off
command(F3 00 00) from adjustment equipment
- Need to transmit the aging off command to TV set after
finishing the adjustment.
- Check DDC adjust mode release by exit key and
release DDC adjust mode
(3) Enter the adjust mode of white balance
- Enter the white balance adjustment mode with aging
command(F3, 00, FF)
* Luminance min value is 200cd/ß≥ in the cool mode( For
LCD)
